Iowa State confirmed his passing on Tuesday. Orr spent the final 14 years of
his near three-decade career as a Division I head coach with the Cyclones. He
led Iowa State to a school-record six NCAA Tournament appearances and retired
in 1994 as the program's all-time winningest coach with a 218-200 record.

Before his stint at Iowa State, Orr coached at Michigan for 12 years (1968-80)
and guided the Wolverines to the national title game in 1976. He also served
three seasons at Massachusetts.

Orr finished with a 466-346 record and 10 NCAA Tournament appearances during
his 29-year career.
